Northern lights

I flushed the medium 2x with ph-ed water at around 6.5 two separate days poured about 3 gallons of water through each time. After that I checked my runoff and the first time my ppm was like 5000 something (ahhh) after flushing again the second time I got my ppm down to around 1100. I started noticing my fan leaves turning yellow letting me know the plant it taking the nutrients from leaves. After watering for the whole week after the double flush I decided to give the girl 10 ml of fox farm big bloom. I haven't noticed any results from that but the trichome development is coming in she's getting a little frosty but they are mostly clear some milky. Just trying to make it to chop.
